Abstract Characterization of the atomic level processes that determine optical transitions in emerging materials is critical to the development of new platforms for classical and quantum networking. Such understanding often emerges from studies of th

Strontium barium niobate (Sr x Ba1–x Nb2O6, referred to as SBN) is a material of interest for making efficient optical modulators due to its very high electro‐optic (EO or Pockels) coefficient. SBN is a ferroelectric with a Curie temperature that

Abstract NbO2 has the potential for a variety of electronic applications due to its electrically induced insulator-to-metal transition (IMT) characteristic. In this study, we find that the IMT behavior of NbO2 follows the field-induced nucleation by
